To all whom it may concern:

Be it known that I, CHARLES A. MGOANN, a citizen of the United States ofAmerica, residing in Blair township, in the county of lVashington andState of Nebraska, have invented certain new and useful Improvements inChurns, of which the following is a specification.

My invention relates to improvements in churns in which an uprightcylindrical receptacle or can is mounted on springs and verticallyreciprocated to agitate, beat and intermix the contents thereof; and theobjects of my improvement are, first, to provide an elasticvertically-vibratory support to carry a churn body or cream can wherebythe contained cream may be agitated and beaten to break the milkfatglobules and separate the butter-fat from the serous parts; second, toprovide a base-seat for the body or can in rigid connection with acoverclamp to also fasten the can in the vibrative end of the support;third, to provide means to alternately draw the top and bottom of thevertically reciprocating can toward the fixed anchorage of its vibratorysupport, whereby the forward end of the contents of the can, in bothdirections of its movement, are thrown inwardly, against its centrifugaltendency, to agitate and completely and continuously intermix saidcontents; fourth, to aiford facilities for varying and adjusting theflexibility of the elastic support according to the quantity or weightof the content of the can; and, fifth, to facilitate the easy connectionof the ends of the horizontally disposed bar-springs with thecan-carriage or clamp and with the fixed support and conserve themagainst breakage or set at these points] These and other minor objectsmore particularly hereinafter set forth, I attain by the mechanismillustrated in the accompanying drawing, in which- Figure 1 is a sideelevation of the churn, the can-seat, can and cover shown in verticalsection; Fig. 2, a top view, parts of the cover and top of the can cutaway; Fig. 3, an underside view; Fig. 1, a vertical section on thebroken line 2 of Fig. 1, giving a front elevation of the stationaryattaching support and spring adjusting contrivance; Fig. 5, a rearelevation of the U-shaped body of the can-clamp or carriage disconnectedfrom the other parts; and Fig. 6, a top view of the cover alone. In allof which views similar reference numerals refer to like parts.

The vertically-vibratory support by means of which the cylindricalreceptacle or can 3 1s longitudinally and vertically reciprocated,comprises the horizontally disposed elastic bars or springs 4 and 5,having the intermediate spiral coils 6 and 7. These springs are fastenedat their rear ends to the stationary attaching support 8 and their frontor vibrative ends rigidly fastened to the can-carriage and clamp. Thestationary support consists of the worked and finished plank havingbeside its other connections the perforations 1, l and 1 by which it islagscrewed or bolted to any vertical wall or post. The clampingcan-carriage consists of a U-shaped body having a long base 9 disposedvertically, a lower horizontallydisposed leg 10 of length to underlieand support the disk 11 attached thereon to form a seat for the can; anda shorter top leg 12 terminated in the knob 13 having a verticalthreaded perforation to take the wheel-screw 14: disposed centrallyabove the seated can. And a curved guide and stop 15 is fastened to theback edge of the diskshaped can-seat to stop the inserted can centrallyon the seat beneath the screw-wheel.

The cover 16 has the annular groove 17 to receive the beaded rim 18 ofthe can 3 into which it closely fits. The cleat 19 on the top of thecover has the central socket 20 to receive the point of the wheel-screwwhen it is turned down to press the cover tightly on the can and fastenthe can seated in the carriage. The cover also has the verticalperforation 21 through which the contents of the can are aerated,examined or tested and is provided with the stopple 22 as shown in Fig.2.

The lateral flange 23 of the U-shaped clamping body is of width equal tothe width of the spring-bars and has curved bends 24 and 24 at thejunctions of the horizontal leg portions with the vertical base of theU. The oppositely curved lugs 25 and 25 are spaced away from the legs ofthe flange to closely receive the spring-bars therebetween and theinterposed forward ends of the springs are fastened to the flange by thebolts 26 and 26 disposed vertically through both. By this means thefront ends of the springs are rigidly fastened to the can carriage andmust fleX at this connection when the carriage is verticallyreciprocated; but the flexure being around the curved lips at the mouthsof the recesses in which the springs are seated said springs arepreserved against set or breakage at these points. The rear end of thelower spring at is similarly fastened to the stationary supportingplank; the upturned vertical end portion 27 is connected with thehorizontal part by a long curve 28 and interposed between the thinstraight chafe-plate 29 and the cap-plate 230 with through bolts 31 and31 to fasten them to the support; and the capplate has the more shortlycurved end 82 overlapping the angle bend in the spring as shown.

To attach the top spring to the stationary support a horizontal cleat 33is bolted across the front of the support; this cleat has the spacedears 3 1 and 3a and the pin disposed horizontally through the ears andacross the space between. The rear end of the spring has a U-shaped bend36 to engage the pin between the ears and form a hinged connectiontherearound, as shown by dotted lines in Fig. 1. An integral end portionof the spring is bent downwardly to form a vertical arm 37 having theforked terminal 38. The threaded rod 39 is attached to the face of thestationary support by the base-plate stO and is disposed horizontallythrough the forked terminal of the arm. A wheel-nut il is mounted on thethreaded rod back of the fork and the tail-nut 12 is mounted on the rodforward of the interposed forked end. By turning these nuts to Hex theforked end of the arm forward the elastic force of the spring isincreased to level up the springs and balance their flexibility againsta heavier content 43 in the can, or to increase the working elasticforce of the springs in any case as may be desired. By attaching thesesprings rigidly at both ends, whereby each must simultaneously flexoppositely at opposite ends, much lighter springs serve to supply therequired elastic force than would be required if the vibrative ends werehinge jointed to the carriage; further they act more positively, moresmoothly and with less noise.

lVhen the can is charged and fastened in the carriage, and if necessarythe springs properly adjusted, the elastic support is highly sensitiveto vertical vibration. By a touch of the hand in alternate pressure andrelease on top of the can cover or carriage they are excited into rapidstrong vertical reciprocation. By this movement the content, which asshown should never on tirely fill the can, is thrown up and down withgreat force alternately against the rel.- atively unyielding cover andbottom. There is a further movement of the carriage and contained can,which renders my contrivance most useful in mixing compounded solutions,such as spraying mixtures for vegetation and the preparation ofbeverages; it being obvious that the size of the contrivance may bevaried as required and different cans for different purposes readilyseated in and removed from the carriage :The intermediate spirallycoiled portions of the springs are disposed as nearly as possible in theplane of vibration and are coiled oppositely in opposite springs.

then in operation the can moves upward the coil of the top springpartially unwinds and expands in size to in effect shorten the distancebetween the opposite ends of the spring; simultaneously the coil of thelower spring is wound closer decreasing its diameter and lengthening thedistance between the connected ends of this spring. By this means thetop of the can is drawn back wardly as it arises, while its bottom isheld outwardly until at the end of the upward movement the can is in theposition indicated by the broken line of Fig. 1. By the reverse ordownward movement the lower end of the can is drawn backwardly and areverse position attained as indicated by the broken line 4:5. Thissudden tilting of the can in opposite directions in connection with thesimultaneous forceful. vertical reciprocation thereof continually andrapidly intermixes and beats together the contents. This action being sothorough and efficient that in churning butter from cream the most rapidservice is performed requiring no other dasher or agitator than theplain containing receptacle or can which is easily filled emptied andcleaned.
